NEXUS Seminar am 26.10.2020
Die aus der Kooperation zwischen der TU Dresden und dem in Dresden ansässigen Institut für Integriertes Management von Materialflüssen und Ressourcen der Universität der Vereinten Nationen (UNU-FLORES) entstandene Seminarreihe geht in die nächste Runde. Schon seit 2015 bietet das „NEXUS Seminar“ spannende Vorträge rund um das Thema nachhaltiges Boden-, Wasser- und Abfallmanagement. Die Veranstaltungsreihe dient dabei nicht nur als eine Plattform für den akademischen Austausch zwischen den beiden Einrichtungen, sondern gibt Wissenschaftlern die Möglichkeit, ihre Ergebnisse öffentlich vorzustellen und zu diskutieren.

Abstract (200 words)
Urbanisation is a global trend. This has led to an increased demand for natural resources, in particular, non-metallic minerals such as stones, sand, and clay. Generally, these materials are traded within regional markets. This close geographical link between the demand for building materials in urban areas and the material supply in the hinterland leads to massive interventions in the natural environment and landscape. These urban-rural linkages can be revealed by applying Material Flow Analysis (MFA) to the built environment. The lecture will introduce a method for quantifying regional material flows by considering the supply and demand of building materials. This will be applied to the Vietnamese case study area of Hanoi and its hinterland province, Hoa Binh. The results indicate a persistent high demand for building minerals in the hinterland province. Depending on the material group (i.e. stones, sand, or clay), demand may exceed the local regulated supply within a few years. In order to safeguard the hinterland from the negative impacts of urbanisation, a new understanding of resource efficiency is needed – one that acknowledges both resource efficiency in the construction and appropriate resource conservation in the provision of the raw materials. This will require the creation of new integrated planning approaches among urban and regional planning authorities.
Biography
Dr Georg Schiller is the acting head of the Research Area “Resource Efficiency of Settlement Structures” at IOER. He studied industrial engineering, received a doctoral degree in civil engineering and urban planning, and is working in interdisciplinary projects with engineers, planners, social scientists, and computer scientists dealing with different topics of resource and climate-related issues of sustainable urban transformation such as circular economy, urban mining, and land use-management.
